Miniature PCB mount power supply meets international medical safety standards

Available immediately from Digi-Key, XP Power introduces the EME05 series of ultra-compact, single output, 5W AC/DC power supplies. Believed to be one of the smallest 5W supplies on the market and available in either an encapsulated or open frame mechanical format, the EME05 measures just 35.6mm x 23.7mm x 17.6mm, taking up minimal space in the end application. The device is approved to the 3rd edition of the international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005. The device provides a reinforced (double) insulation with 4000 VAC input/output isolation and two means of patient protection (2 x MOPP). The convection-cooled series provides eight single-output models covering all the popular nominal outputs from 3.3VDC to 48VDC. A peak load capability allows up to 130% of the rated output power to be available for up to 30 seconds. This is ideal for accommodating application start-up where a higher load is required for a relatively short period. This approach allows a designer to save valuable board space and cost rather than having to specify a higher rated and potentially larger power supply in order to meet peak loads. The device has universal input and offers full power across the complete input range of 90VAC to 264VAC without any derating. All models offer Class II construction so no earth/ground connection is required. The units meet the EN55011 Class B EMI standard for conducted and radiated emissions. No additional filtering components are required, saving PCB space and BOM costs. Capable of delivering full power up to +50C and operate across a wide temperature range from -25C to +70C, the device can be used in most environments without the need for any additional heat sinking or forced airflow.
